R help - Feb 2008 - Replacing a character string when finding substring match

Dear R-experts,

  I need to replace the values of a vector(tx) with a
word ('Vehicle') when the value of the vector contains
the word 'vehicle'. Sometimes, the value could be 'MCT
vehicle', or 'control-vehicle', etc.
  I tried gsub like this 

treatment<-gsub('vehicle','Vehicle', tx, 
ignore.case=T)

   But then I end up with values like 'MCT Vehicle' or
'control-Vehicle'. I want the values to be one word:
'Vehicle'.

    

Thank you in advance for any help.

Try this:

x[grep("vehicle", x, ignore=T)] <- "Vehicle"
